The 3028, 3033 and 3040 are all really exactly the same card, the only
difference is the speed of the processor. The card is very similar to
the A4000 version (please see Warpengine 4040/4033/4028 for more
information) except that it had the INT2 jumper line and also only had
two SIMM sockets as opposed to four which were fitted in a very low
profile to fit inside the A3000. This card requires Kickstart 2.04 or
higher to work in the A3000. It also includes a Fast SCSI-II controller
(NCR53710) which provides a 50pin internal SCSI connector. The
WarpEngine also supports an 030 fall-back mode. Note, this mode
probably only works if you also have an 030 on the motherboard, eg most
A4000's don't. You can connect a switch to JP2 with the clock jumper
set to internal to disable the RAM and on-board SCSI which may help
with very old games.
